Role of Some Plant Growth Promotory Bacteria on Enhanced Fe Uptake of Wheat

Communications in Soil Science and Plant Analysis (2017)

Sachin Kumar Vaid Arun Kumar Anita Sharma P. C. Srivastava Arvind Kumar Shukla

The quest for plant growth promotory bacteria that can help in sustainable agriculture has increased in the recent years owing to increasing cost of fertilizers. In the present study, the potential of three isolated bacteria having plant growth promotory effects in mobilizing the indigenous soil iron (Fe) in two different varieties of wheat was evaluated. Three bacterial isolates belonging to the genera Burkholderia and Acinetobacter were evaluated singly and in combinations for Fe uptake of wheat in a net house study. Results showed that bacterial isolates when used in combination performed better in comparison to their individual use. These isolates significantly increased the mean Fe concentration in grains and straw by 34.0% and 52.4% over the uninoculated controls and also increased the total Fe uptake per pot in comparison to uninoculated controls. The bacterial inoculation also showed a positive impact on the bioavailability of diethylenetriaminepentaacetic acid (DTPA) extractable Fe in soil.

Effective zinc mobilization to rice grains using rhizobacterial consortium

Israel Journal of Plant Sciences (2020)

Sachin Kumar Vaid P.C. Srivastava S. P. Pachauri Anita Sharma Deepa Rawat

Low Zn in staple food grains like rice is closely related to large scale Zn malnutrition in many countries of the World. Zinc biofortification of rice grains by some cost effective agronomic method is important for low income farmers. To explore the possibility of enhancing the bioavailability of Zn in rice grains besides higher yields of two cultivars, the combinations of varying Zn fertilizer doses with or without inoculation of rhizobacteria consortium under split plot design set up were evaluated in two years field trials. Microbial inoculation + 5 kg Zn ha -1 to I year rice crop resulted in the highest number of effective tillers, grain yields, Zn concentration and uptake in grains and straw and total Zn uptake in both years. Grain yield of rice during two years increased by 19.7-27.9 and 17.1-20.4 percent over control under treatments receiving microbial inoculation + 5 kg Zn ha -1 to I year rice and 5 kg Zn ha -1 alone to I year rice crop, respectively. The highest concentration of Zn (10.9-19.1 mg kg -1 ) and the lowest concentration of phytic acid (18.5-25.3 g kg -1 ) in dehulled rice grains were recorded with soil application of 5 kg Zn ha -1 ; however, the values were at par with those observed under microbial inoculation + 5 kg Zn ha -1 (12.0-17.0 mg Zn kg -1 and 19.2-26.9 g phytic acid kg -1 ). The percent utilization of soil applied Zn increased with microbial inoculation in both the years and it was relatively higher in NDR 359 as compared to PD 16.

Impact of Production Practices on Organoleptic Intensity Scale of Different Rice Cultivars

Journal of Pharmacy and Nutrition Sciences (2015)

Amit Kesarwani Madhu Sharma Sachin Kumar Vaid Shih Shiung Chen

The purpose of this research was to relate mean organoleptic scores of organically and conventionally grown rice (n = 5) in japonica cultivars (Taikeng No. 16 and Kaohsiung No. 139). The 0-7 organoleptic scale is used in trials to measure the agronomic practices impact on sensory attributes of rice cultivars. However, the precise relationship between farming system and organoleptic analysis of rice remains independent variables. Judges (n = 10) used a common 0-7 scale to report the 6 sensory attributes viz. appearance, aroma, flavor, cohesion, hardness and overall acceptability while keeping cultivar Taikeng No. 9 as control. The scale ranges from – 3 to + 3 as very poor to excellent. The study demonstrates sensory attributes as inherited trait of rice; while no improvement found in cooking and eating quality under seasonal or agronomic variations. Interestingly, the aroma was reported as only better parameter when grown under organic farming compared to conventional farming (– 0.49 and – 0.62 over control, respectively). Also, the positive co-relationship exists between amylose content and organoleptic analysis while antagonistic link to crude protein content. The study cleared that management method, per se, did not influence any flavory attributes and detected no changes by the sensory panel. Further descriptive analysis needed with different conditions such as variety, degree of milling, growing location and moisture content which also played significant role in determining flavor and eating quality of rice cultivars.

Enhancement of Wheat Growth and Zn Content in Grains by Zinc Solubilizing Bacteria

International Journal of Agriculture Environment and Biotechnology (2013)

Deepak Joshi Geeta Negi Sachin Kumar Vaid Anita Sharma

Two bacterial isolates (B1 and B2), recovered from the rice rhizosphere produced siderophore and indole acetic acid and solubilized insoluble phosphate, ZnO and ZnSO4.7H2O. Based on routine biochemical tests, both the isolates were characterized as species of Pseudomonas. A shift in pH from 7 to 5 was observed in minimal medium supplemented with Zn compounds after 15 days of bacterial growth. Isolate B1 solubilized maximum amount of ZnO (1.348ppm) after 15 days of incubation. In a pot experiment on wheat (PBW 373), application of bacterial isolates and their consortium with ZnSO4.7H2O @ 5mM significantly enhanced plant height, chlorophyll, grain number per plant over control after 90 days of sowing. Consortium (B1B2) treated wheat plants showed 31% increase in grain Zn over control. HPLC analysis of the root extract of bacterized wheat plants showed the dominance of oxalic, maleic, á-ketoglutaric and fumaric acid. Presence of higher amount of valine and leucine, sugar, protein and phenolic compounds was observed in the root extracts of consortium treated wheat plants than control.

Sachin Kumar Vaid Bhavesh Kumar Ashish Sharma Arvind Kumar Shukla P.C. Srivastava

A comparison study between the isolated indigenous bacteria and chemical Zn fertilizer (ZnSO 4 .7H 2 O) was conducted to evaluate their potential to augment Zn nutrition of Zn responsive (NDR 359) and Zn non responsive (PD 16) varieties of rice under the green house.Three bacterial strains namely; BC, AX and AB isolated from a Zn-deficient rice-wheat field belonging to the genera Burkholderia and Acinetobacter were investigated for the growth promotion and Zn uptake in rice plants.The plant growth promotory properties such as Zn solubilization and IAA production of the isolates was checked in a previous study.These three isolates when used individually or in combination were found effective in significantly increasing the mean dry matter yield/pot (12.9%), productive tillers/plant (15.1%), number of panicles/plant (13.3%), number of grains/panicle (12.8%), grain yield (17.0%) and straw yield (12.4%) over the control and Zn fertilizer treatment, respectively.Bacterial inoculations also significantly enhanced the total Zn uptake/pot (52.5%) as well as grain methionine concentration (38.8%).Effect of bacterial treatments on the bioavailability of Zn was assessed by estimating the levels of phytic acid in grains.A reduction of nearly 38.4% in phytate: Zn ratio in grains was observed under bacterial inoculations.

Residual effect of zinc applied to rice on zinc nutrition of succeeding wheat crop inoculated with zinc solubilizing microbial consortium

Israel Journal of Plant Sciences (2018)

Sachin Kumar Vaid P.C. Srivastava S. P. Pachauri Anita Sharma Deepa Rawat

Large scale deficiency of Zn results in low crops yields and the problem of Zn malnutrition in humans and livestock. To economize crop production on Zn deficient soils, two-year field experiments were undertaken with two wheat varieties to evaluate the performance of seed inoculation with a consortium of three bacterial strains in combination with varying doses of Zn fertilizer applied to 1 year rice crop on yields, Zn concentration and Zn uptake of wheat. Seed coating of wheat with bacterial consortium significantly increased grain yields, Zn concentration and uptake in grains and straw and total Zn uptake over the control. It also helped to increase the apparent recoveries of soil applied Zn fertilizer to 1 year rice by succeeding wheat crops and DTPA extractable Zn in soil after 2 year wheat in comparison to the control. Seed inoculation in combination with low dosage of Zn also significantly decreased phytic acid: Zn ratio but increased methionine concentration in wheat grains.

Zeolite Farming: A Sustainable Agricultural Prospective

International Journal of Current Microbiology and Applied Sciences (2018)

M.S. Mahesh Jencymol Thomas Arun Kumar B. S. Bhople N.V. Saresh

India is a developing nation practicing intensive agriculture for fulfilling the needs of more than eighteen million peoples, for which huge and imbalance amount of fertilizer has been used. Consequently, soil quality deteriorates and inevitable loss of soil microbial diversity. In recent years zeolites a natural aluminosilicate was studied extensively as soil amendment as it increases the soil-nutrient surface area and extend the magnitude of nutrient use efficiency in farming systems. Zeolites types vary in their chemical composition and structure and may have different impact on soil nutrient availability to plants. Slow releases of nutrient, water holding capacity, enhancing soil microbial diversity, ion exchange capacity are the major areas of current research. In this review we present the zeolites types and explored their role in nutrient dynamics.
